This invention relates to husking rollers which are grouped in pairsand. mounted in the husking machine whereby the husks are removed fro-mthe ears of corn passing between the pairs of rotating rolls.

One of the objects of the invention is to form each roll of the pair ofrolls with a rubber casing carrying axial peripheral grooves and mountthe rubber casing on a square shaft to prevent the casing from slipping.

Another feature of the present invention is to make the rolls of eachpair of the same size, place husking pins in certain of the grooves onone roller, and have the grooves of each roll register with the groovesof its companion roll thereby causing the ribs between the grooves toengage in abutting relation and as a result providing cleaner husking ofthe ears with less shelling of the corn.

With the foregoing and other objects in view the invention consists of anovel combination, construction and arrangement of parts as will behereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown the preferred form of theinvention, but it is to be understood that changes, variations andmodifications may be resorted to without departing from the spirit ofthe claims hereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views:

Figure 1 is an elevation of one of the improved rollers shown on theright in Figure 3 of the drawings.

Figure 2 is a section taken substantially on line 22 of Figure 1.

Figure 3 is an end view showing how the pair of rollers will operatewith each other in a husking machine.

Figure 4 is a view of one of the bolts.

Figure 5 is an elevation taken a quarter of a turn from Figure 1.

Figure 6 is a perspective view of the metal shaft.

Figure 7 is a perspective view of the rubber part of the roll on theleft in Figure 3 of the drawings.

In the drawings, A indicates one of a pair of companion rolls and Bindicates the other of a pair of companion rolls which are adapted forbeing rotatably mounted in a husking machine (not shown). This pair ofhusking rollers A, B rotate in unison and are of the same size. Eachroller is formed in the same manner with the exception of the huskingpins l l and it is believed that a description of the one will clearlyteach the formation of the other.

The shaft l of each roller has its major portion of rectangular shape incross section with its ends reduced and rounded to form the trunnions 2,the shaft being formed of metal or any other suitable material. Therubber part of the shaft is shown at 3 and has a square bore 4 forreceiving the rectangular portion of the shaft l and the two parts areconnected together by the bolts 5, one of which passes through each endportion of the roller. The shaft 1 is formed with holes 6 for receivingthe bolts and the rubber member 3 also has the holes I registering withthe holes 6 in which the bolts are mounted. It is pointed out that thebolts extend diametrically through the shaft and the rubber casing 3.Nuts 8 are threaded on the bolts, and the threaded part of each bolt issplit as shown at 9 so that this end can be clinched over the nut.

The rubber casing or member 3 is formed with longitudinally extendinggrooves l0, preferably four in number and of the shape shown and theheads of the bolts and the nuts are located in the opposed grooves. Bothrolls A and B have the above described characteristics.

In only one of the husking rolls A are disposed the husking pins II. Thehusking pins II are arranged in an aligned series in the one groove andanother aligned series in the diametrically opposite groove. The seriesof pins in the one groove is offset with respect to the series of pinsin the opposite groove. The series of pins in the roller A are disposedsubstantially at right angles with respect to the bolts 5. Each pin isformed with a head I2 and a portion of its shank embedded in the rubbercasing or member 3 leaving a projecting portion extending into therespective grooves substantially flush with the ribs between thegrooves. It will be seen by referring to Figure 2 of the drawings thatthe heads l2 of the pins bear against the face of the shafts 2.

As shown in Figure 3, the rollers are so arranged that the ribs formedby the grooves I0 will coact with each other during the rotation of therollers, and these rollers rotate in unison.

Due to the fact that the husking pins are simply held by the rubber,they are not stationary and thus they will pick the husks from the earsjust as eiiiciently when the husks are wet as they will when the husksare dry.

These rubber covered rollers will clean practically all husks from theears with the minimum amount of shelling of the corn. When the rubberparts become worn, it can be readily removed 10 husking pins embedded inthe rubber and having their points projecting into the grooves and theheads thereof disposed between the inner side of the rubber coveringand. the shaft.

2. A husking roll comprising a shaft of noncircular shape in crosssection and a rubber covering for the shaft having a bore ofnon-circular shape to receive the shaft, said rubber part havinglongitudinally extending grooves therein and husking pins embedded inthe rubber and having their points projecting into the grooves and theheads thereof disposed between the inner side of the rubber covering andthe shaft, and bolts for detachably connecting the rubber member to 10the shaft.
